Qualifications

There are a ton of great Python projects out there, but what makes an
application "Awesome™"? Please check that all of the following criteria apply:

• Free software with an online source repository.
• Using Python for a considerable part of their functionality.
• Well-known, or at least prominently used in an identifiable niche.
• Maintained or otherwise demonstrably still functional on relevant platforms.
• An application, not a library or framework.

We are currently in the process of a re-thinking and re-doing of the application in the v0.6.x series to make it a serious, usable, useful and powerful, yet simple, image editor -hence the two repos. However, the v0.5.x series (the second link) is still usable as-is and has received very good feedback so far even though it is beta software. Therefore, I believe it still meets the Qualifications above.

To go a bit further in convincing, I do believe this is a unique (and quite ambitious) project and does/will showcase what can be done with Python and it's ecosystem (which I think is one of the goals of this list). Thank you for considering.

Start with projects.yaml, using its comments and existing examples to understand the entry format. Review the Gimel Studio repository and home links listed in the issue, then add the project as a short entry if it meets the stated qualifications; done means the listing is present with the relevant links and description.
